When allocating in MN all the allocations are done before deductions. So the income should be what was actually earned in MN.
For the WI form OS, first once you complete your MN non-resident return in TurboTax the WI form OS automatically populates from the MN return.
If you have to complete the lines yourself, the income taxed by the other state is before deductions or exemptions and if only wages then it be the income earned in MN.
